Sažetak
In the period of 1988-1990 in the experimental field of Tobacco Institute in Cerrik a trial was carried out on the effect of climate in the region of Cerrik upon Virginia Tobacco. A special attention was paid to the morphological characteristics, the length of the vegetational period, the yield and the quality of the raw and chemical features of cured leaf. During the three years of our investigations the average temperatures in the period of vegetation are considered suitable for Virginia tobacco, whereas rainfalls and their distribution could be considered unsuitable. In 1989 the rainfall was 61% and 40% more than, respectively, in 1988 and 1990. In 1990 it was almost as in 1988 but had a more regular distribution. As the result of this climatic conditions there was high significantly yield in 1989 49% and in 1990 44%, as compared to the year 1988, and significantly better quality in 1989. The length of the growing period was significantly less in 1989, whereas the leaf number is significantly greater by the dry years (1988,1990). In 1989 significantly greater length of middle leaf was also found. Chemical analysis of cured tobacco leaf showed higher content of nicotine and other nitrogenous compound in dry condition of 1990 and lower content of reducing sugar, than in 1989. Based on investigations carried out the following statements might be drawn: In the region of Cerrik during the vegetation period the mean air temperature is adequate for high growth and the development of tobacco Virginia plant, but there is a little rainfall and its very irregular distribution. The Virginia tobacco grown under this condition of insufficient precipitation is characterized by a relatively low productional and qualitative possibilities, so a successful cultivation of this tobacco requires the application of irrigations.
